Producer Nate 'Danja' Hills, who with Timbaland produced Justin Timberlake's 'FutureSex/LoveSounds' album, has been working on the next Madonna album.

Danja has told EW to expect "a classic Madonna album".

Danja, who is co-producing some of the tracks with Timbaland, says that the album is "very up-tempo, upbeat and urban".

The first single from the album, featuring Justin Timberlake, is called '4 Minutes To Save The World'. Madonna and Timberlake made a video for the single in London last month.

Madonna plays a pimp who rescues the planet in the video.

The yet-to-be titled album will be Madonna's 11th studio record. Word leaked late last year that the album would be called 'Licorice' but that has since been denied by the Material Girl.

The album will be released in April.
